Plextor, a leading supplier of optical and storage devices, announced today a new 4x Blu-ray DVD-RW drive using the SATA interface – the PX-B910SA. Building on the success of PX-B920SA, the PX-B910SA drops the support for HD-DVD presented in the above mentioned model and becomes a Blu-ray drive only. Other than that, read/write specs for other media formats remain the same (listed below). The drive is expected to retail in Japan for about JY45,000 ($430).
